A new LED light fixture is secured to the side of a lift as crews replace existing street lights August 1, 2011 in Las Vegas, Nevada. The new energy-efficient fixtures are expected to reduce the city's annual electricity use by eight million kilowatt hours, saving about USD 400,000. The city estimates the LEDs will last about 15 years, nine years longer than the current lights. Funding for the project comes from federal energy conservation bonds and an American Recovery & Reinvestment Act grant. The city plans to replace all of its 50,000 streetlights after more funding is secured. (Photo by Ethan Miller/Getty Images)

It is amazing how much the humanity can change the face of the earth. Not only can it create huge craters, which look a lot like craters from meteors, they leave a big enough impact that it can be seen from space. Though this crater, caused by a massive explosion on 1 July 1916, looks large, being 90 feet deep and 300 feet across; it is nowhere big enough to be viewed for space. A common misconception is that the Great Wall of China can be seen from space. In reality, however, it is impossible. Not only is it of the same color as the earth near it, it is also not that wide. Deforestation, on the other hand, can be clearly seen from space. Also, at night, all the lights that the large cities produce are also very visible.
